Specification of Letters Patent.

Patented J an. 14;, 1919.

Application filed May 4, 1916. Serial No. 95,366.

To all whom it may concern Be it known that I, ANTON AUGUST HAAHR, a subject of the King of Denmark, residing at Copenhagen, Denmark, have invented certain Improvements in Pegging- Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for pegging boots and shoes. For the purpose of illustration the invention is shown herein as embodied in a machine of the type shown and described in United States Letters Patent No. 581,066, granted April 20, 1897, on application of John F. Davey and Sherman \V. Ladd, although the utility of the invention as a whole or various features thereof in connection .with machines of other types is recognized.

The general object of the present invention is to provide an improved machine for inserting pegs in boots and shoes. More particularly the invention aims to provide an improved pegging machine of the type set forth in the above mentioned Letters Patent.

Machines of the type disclosed in said Letters Patent are provided with a work supporting horn on which are carried the cutters for severing the pegs and the operating mechanism for those cutters. In the illustrated machine the work supporting end of the horn comprises a button or cap plate through which the ends of the pegs project after being driven, the cutters operating below the cap plate to sever the projecting ends of the pegs. It is important that the pegs should be cut off as closely as possible to the work. To accomplish this result the center portion of the horn cap plate must necessarily be as thin as practicable, and the construction and arrangement of the cutters and their operating mechanism must be such as to enable them to sever the peg as nearly as possible in the plane of the cap plate. At the same time the cap plate must be sufliciently strong to resist properly the blows of the awl and peg driver. A feature of the present invention consists in a novel construction and arrangement by the use of which, without sacrificing any of the wellknown advantages of prior constructions, the pegs may be cut oil more closely to the material through .which they have been driven Without in any way'decreasing the resistance offered by the cap plate to the blows of the awl and peg driver.

On the contrary, in accordance with another feature of the invention the illustrated construction and arrangement are such that the horn and particularly the horn cap ofi'ers substantially greater and more effective resistance against the blows ofthe peg driver than in machines as heretofore constructed.

It is furthermore important, especially in operating upon certain kinds of ,Work, that the transverse dimension or diameter of the upper part of the horn which is inserted in the shoe to be operated upon should be as small as it can be made consistently with proper construction and operation of the peg cutters and their operating mechanism and without interfering with the proper operation of the awl. In accordance with a further feature of the invention, by reason of the compact construction and arrangement of the cutters and cutter operating mechanism, the illustrated horn button and the upper part of the horn tip are substantially smaller than has heretofore been possible. This is of especial importance when the machine is used in operating upon work such, for example, as shoes having pointed toes or shoes of small sizes, including particularly infants and childrens shoes. At the same time the illustrated-horn is equally well adapted for operating upon shoes of large sizes.

Another feature of the invention resides in the provision of cutters which are so constructed and arranged that they invariably shear off the projecting ends of the pegs cleanly and .With the minimum expenditure of power. It has heretofore been the practice to make horn peg cutters of wedge shape, and due-to the cutters being relatively thick adjacent to the cutting edges, said cutters have sometimes operated to crush the projecting ends of the pegs and to break them off rather than to cut them, thereby necessitating subsequent rasping of the points of the pegs. It has been found in practice that cutters constructed and arjusting the peg cutting knives to compensate for wear, thusboth prolonging the lives of the knives by making it practicable to use knives even after they have been ground repeatedly and at the same time making it possible to obtain a clean out even with badly worn knives.

Other features ofthe present invention in clude a novel construction and arrangen' ent for mounting and guiding the peg cutters, improved means for mounting the horn cap on the detachable horn tip, and novel mechanism for operating the cutters yielding to prevent breakage.

These-and still other features and advantages of the present invention, designed to provide pegging machine which .will be stronger, simpler, and more effective in op eration, and in which the parts likely to need adjustment or replacement will be constructed and arranged to be more accessible and'more conveniently replaced or adjusted than has been possible heretofore, will be apparent from the following detailed description read in connection with the appended drawings which illustrate a preferred embodiment of the invention incorporated in a machine of the type above mentioned.

Referring to the drawings Figure 1 isa side elevation of a part of a machine embodying the invention showing the horn and the horn support, the cutter operating mechanism and enough of the peg driving mechanism to make the invention readily understandable, the horn being shown partly in section Fig. 2 is a side elevation of the horn in section;

Fig. 3 is a view in angular perspective of one of the cutter holders and the fulcrum for the cutters; and

Fig. 4 is a view in perspective of the cutters.

As hereinbefore stated, the illustrated machine is. a machine of the type shown and described in the said United States Letters Patent. Conveniently, and as shown, ex-

testes? cept as hereinafter described in detail, the machine may be substantially as disclosed in said Letters Patent. Accordingly only. such parts of the illustrated machine will be described hereinafter as are necessary to a clear understanding of the present invention and referenceshonld be had to the said Letters Patent for details of construction not fully set forth herein. 7

The machine comprises a column which supports the main framework or head A of the machine. The head A carries the awl B, peg driver C and the actuating mechanism therefor, these parts, as shown, being substantially like those illustrated in the patent above mentioned. The column has secured to it a horn supporting sleeveD carrying a hollow horn E comprising a mainor body portion F, a tip portion G' detachably secured to the body portion, as will be hereinafter explained, and a cap plate or cover 2 removably mounted on the top of the horn tip. The cap plate 2 has an opening 3 to receive the ends of the pegs as they are driven. The horn tip G is secured to the main or body portion of the horn by means of four screws 1. The cap plateior cover 2 is provided with a dovetail receivedv in a (love-tailed slot in the horn tip G. For removably attaching the cap plate 2 to the horn tip G there is provided a forked piece 4&- secured to the horn tip G by ascrew 5 threaded into a part 6 in the horn tip G. In the operative relation of the parts the fork t, by embracing the depending part of the cap plate 2 on both sides, securely holds the cap plate against removal from the horn, while merely by removing the single screw 5, the cap plate 2 may be quickly and easily removed for replacement.

The cutting mechanism which is carried in the top of the horn comprises knives 7 and 8 arranged to operate in a cylindrical cavity in the lower part of the cap plate or cover 2, the cap plate or cover 2 having a central aperture or opening through which the awl and driver pass and through which the end of each driven peg projects, the cutters operating to cut off the ends of the pegs immediately beneath the cap plate. The knives 7 and 8 are carried upon annular holders, one of which is shown at 13. The holders are loosely fulcrumed upon a fixed stud 9 located, as shown, just below the cap plate 2, the stud 9 in accordance with an important feature of the invention being separated from the lower face of the cap plate 2 by a distance substantially less than th diameter of the cap plate Qand less than the distance traversed by the cutting edge of each of the knives. The stud 9 (see Fig. 2) has its ends loosely received in vertical slots opening upwardly at the upper end of the horn tip. The rim of the cap plate overlies the open upper ends of the said slots. The ends of the stud are cut away on their upper sides which are spaced from the rim of the cap plate. The bifurcated por tions of the forked piece 4 pass between the rim of the cap plate and the ends of the stud 9. The forked piece 4 constitutes a common securing means for cap plate 2 and stud 9, and upon removal of piece 1 the cap plate, stud, cutter holders, and cutters may be bodily removed from the tip. The removal of the stud, cutter holders, and cutters is made possible by the loose connection shown in Fig. 2 between the cutter holders and their operating levers. The stud 9 is provided with an opening 10 through which pass the severed portions of the pegs. The knives 7 and 8 have curved cutting end portions and are shaped in a circular curve of comparatively small diameter (Fig. 4). The annular holders which, as above stated, are fulcrumed upon the stud 9 are provided with recesses to receive pins 11 and 12 by which the knives 7 and 8 respectively are mounted in the knife holders.

It will be observed that, by reason of the described construction and arrangement of the knives 7 and 8 and the knife holders with relation to each other and in respect to their fulcrum 9 and by reason of the location of the fulcrum 9 in close proximity to the cap plate 2, upon actuation of the knife holders a rocking movement is imparted to the knife holders and operative movement is thereby given to the knives 7 and 8 in directions to cause the knives 7 and 8 to approach each other in a curved path of a radius considerably smaller than the radius of curvature of the plane of the relatively flat cap plate 2. Necessarily the central portion of the cap plate 2 adjacent to its central opening must be as thin as practicable in order that the pegs may be cut off as closely to the work as possible. The construction and arrangement just described not only facilitates cutting off the pegs closer to the work by making it practicable to reduce substantially the thickness of the central portion of the cap plate but at the same time makes it possible to strengthen the cap plate materially by thickening the edge portions of the cap plate as indicated at 57 Fig. 2, thus enabling the cap plate and consequently the horn to offer a greatly increased resistance to the impacts of the awl and the blows of the driver as compared with cap plates of uniform thickness throughout. Also by reason of the great compactness of the cutter mechanism due in part to the small radius of turning movement of the cutters, the illustrated cap plate or button and the upper part of the horn tip are substantially smaller in diameter than the corresponding parts of pegging machines as heretofore constructed.

As hereinbefore stated, this greatly facilitates the operation of the machine especially when the machine is used for pegging shoes having pointed toes or shoes of small sizes, particularly infants and childrens shoes, without, however, diminishing the usefulness of the machine in operating upon shoes of even the largest sizes. At the same time and in accordance with another feature of the invention the lower surfaces of the cap plate may be and are disposed in the plane or path of movement of the knives and the fulcrum stud 9 is constructed, as shown in Fig. 3, to present an annular surface 59 substantially complemental to the lower surfaces of the cap plate, the lower surfaces of the cap plate and surface 59 constituting an arcual guideway for the cutters in which the cutters are fully supported throughout their whole 0perative movement. The knives 7 and 8 are formed as relatively thin blades of substantially uniform thickness throughout and with relatively short beveled cutting surfaces (see Fig. 4). The opening 3 of cap plate 2 is of slightly greater diameter than the peg to be cut. The distance between the cutting edge of each of the knives and the point of intersection of a radial line, drawn through the point where the beveled cutting surface meets the inner surface of the knife, with the outer surface of the knife is less than the radius of the opening 3 and consequently less than the radius of the peg to be out. By reason of the above construction, the knives themselves pass into the pegs and cut them cleanly. A sharpened cutting edge can be maintained thereon by grinding down the beveled ends. For operating the knives 7 and 8 through the knife holders each knife holder has a forked extension 16, (Fig. 3) the extensions 16 being arranged to embrace respectively the ends of two levers 18 and 19 fulcrumed on a pin 55 fixed in the horn tip. The jaws 18 and 19 have extensions 20 and 21 below their fulcrum point 55, the extensions 20 and 21 of the levers 18 and 19 being crossed at 60. A fork comprising two flat arms 28 carries three rolls 22, 23 and 2 1 fulcrumed respectively on pins 25, 26 and 27, the rolls 23 and 24 being located, as best shown in Fig. 2, to engage the outer sides of the extensions of the members 20 and 21 substantially at the point of crossing of these levers and the roll 22 being disposed in the opening between the members 18 and 19 just below their pivot 55 to have wedging engagement with the extensions of the members 18 and 19 upon their inner sides. The fork 28 is reciprocated by a rod 29 guided in the cylindrical part 30 of the horn. On one end the rod 29 carries a pin 31 carrying a roll, said pin passing through an oval slot 32 in a triangular piece 33 fulcrumed upon a pin 34 in the horn. The triangular piece 33 is provided with another oval slot 35 through which passes a pin 37 carrying a second roll, the pin 37 being attached to the end of a rod 36 and the opening in the horn through which the triangular piece 33 moves being closed by a cap 38 screwed to the horn. The rod 36 which is guided in the hollow column of the horn ishinged to a" link 39 adjustably connected to an operating rod 51.

Upon movement of the rod 51 the rod 36 is operated through its described connection with the triangular piece 33 to rock the member 33 about its fulcrum 34, thereby rea ciprocating the rod 29. Movement of the rod 29 one way operates by means of the rolls 23 and 24 to draw the lower ends of the extensions 20 and 21 toward each other, thereby separating the jaws 18 and 19 and rocking the knife holders about their fulcrum stud 9 to impart relative cutting movement to the knives 7 and 8 in timed relation to the peg driving mechanism to cause the knives to cut off the projecting end of a driven peg close to the under side of the cap plate 2.

To provide for ready adjustment of the normal position of the knives relatively to each other to alter the limit of normal approach of the wives and thereby, for example, by moving the knives nearer together to compensate for wear of the knives, as above stated, an adjustable connection is provided between the link 39 and the rod 51. In the illustrated construction this adjustable connection comp "ises a head piece 10 to which the link 39 is pivotally connected, which head piece is hollow and receives a screw 42 surrounded by a spring 4,1, the upper end of the screw having a projecting head 13 by which it may readily be turned to effect the desired adjustment through an opening in the horn normally covered by a cap 52. A milled flange 44 is carried by said screw 42 below the head 43, and the head piece 40 is provided with internal projections 44:. A block 18 disposed in the horn cavity and free to move vertically but secured against turning movement is threaded to receive the screw 42. The lower end of the block 18 comprises a fork 49 the arms of which are connected by a stud 50 to which the operating rod 51 above mentioned is pivoted.

Upon turning the projecting head of the screw 42 and consequent movement of the screw 42 relatively to the block or. nut 48 the distance-between the head piece 10 and the nut 48 may be varied as desired, thereby increasing or diminishing the effective length of the operating parts through which the triangular piece 33 is rocked, whereby the normal distance between the cutting edges of the knives 7 and 8 can be varied. This enables the knives to be adjusted to commains? pensate for wear and insures clean cutting even when the knives have been badly worn or greatly ground down.

The spring 41 provides a yield for the knife operating mechanism whereby, if the knives encounter any abnormal or unexpected obstacle before they have completed a cutting n'ioveme'nt, the spring 41 will yield to prevent damage as, for example, in the event that an awl breaks and a; part of the awl remains between the knives. The reverse movement 'of the knives is effected by the engagement of milled flange 14: withprojections 44.

The head piece 4:0 has a horizontal projection 46 provided with a hole in which is carried a spring pressed plunger 47 normally pressed into engagement with the milled flange 4% by a spring i5 thus preventing accidental turning of the screw while permitting the screw to be readily turned by its head 43.
